To all whom it may concern:

Be it known that we, JOHN C. Hnen'nn and FREDERICK H. DANIELL, citizensof the United States, residing at Providence, in the county ofProvidence and State of Rhode Island, and Franklin, in the county ofMerrimack and State of New Hampshire, respectively, have inventedcertainnew and useful Improvements in Dyeing Apparatus, of which thefollowing is a specificatlon.

Our invention is a dyeing apparatus for use in treating textiles withliquor or gas in .dyeing, mordanting, bleaching, scouring, washing,drying or other similar processes.

Our invention relates particularly to a machine for treating yarn andother fibrous material wound into cops or bundles and consists ofimprovements in the method of handling the material during the processesof treatment; in the means for confining the yarn under pressure tosecure a uniform density of all parts ofthe mass without disturbing theconformation of the packages or the relation of the coils of winding;and for regulating and controlling the flow 'of the fluid to subject thematerial 'to a thorough permeation.

Our invention is fully set forth in the following specification,illustrated by the accompanying drawings, in which Figure 1 is aperspective view of the complete apparatus; Fig. 2, a vertical,transverse, sectional view of the keir or dyeing chamber; Fig. 2), aplan view of the pump and pipe connections which regulate the fiow offluid; Fig. 4, a vertical, transverse, sectional view of the heatingchamber; Fig. 5, a plan view of the sliding compression head; Fig. 6, asectional view of one of the units on which the material is supported;Figs.v 7, 8, 9 and 10, views showing details of construction.

The apparatus in general consists of the as shown in Fig. 1: A is thekeir in which the material is contained during the dyeing or otherprocess; B is a .supply or mixing tank which receives the dyeing liquoror other fluid; C is a heating chamber in which the fluid is given theproper temperature and D is a centrifugal pump which causes acirculation of the cured in place by the spindle 12 are fluid from theheating chamber into the-keir and back again, through the arrangement ofpipes and valves hereinafter explained.

As shown in Fig. 2, the keir A is prefer ably of cylindrical form with adome-shaped top 2 and a similarly shaped convex bottom 3.

Between the cylindrical portion and the con-' vexbottom 3 is adiaphragmor false-bottom consisting of a plate 4 fastened to theangle-iron rings or flanges 5 and 6 which extend around the outside ofthe keir and are riveted thereto. Bolts 7, 7, etc., extend through theflanges 5 and .6 and the rim of the plate 4 tosecure the latter inposition. The dome or top 2 is formed with a flange 8 fitted to theinside of the cylindrical por-- tic-n of the keir and riveted thereto,and all of these joints are filled with gaskets or other suitablepacking to prevent leakage.

On the front of the keir A is a door a, shown in Fig. 1, adapted toclose an opening through which the material to'be dyed is passed intothe keir. The door -ais sebolts a passing through slots in the lugs aand adapted to receive the door snugly against its seat. Suitablepacking or gaskets are provided to make the door tight where it fits itsseat.

Secured to the top of the dome 2 is a ring'plate 9 to which is attacheda yoke 10' with a bearing at 11 for the plunger spindle 12. In thebearing 11 is a sleeve 13 counterbored at 14 and threaded internally vat15 to engage the thread of the spindle 12. The sleeve 13 is formed witha shoulder 16 abutting the bottom face of the bearing 11, and turneddown ,at 17 to enter the bore of the ub of'a hand-wheel 18. Thehand-wheel 18 is preferably secured to the sleeve 13' by a pin 19 andthreaded end of the. sleeve.- A usual form of stufling-box 21 is securedin a central bore in the dome 2 by means of the nut 22 screwed on to itsthreaded end and abutting the inside of the dome. The spindle 12 extendsdownward through the stufling-box 21 and carries at its lower end thecompression head 23, shown in plan view in Fig. 5.

RHODE ISLAND, AND FREDERICK H. lJANIELL, OF MARY B. DANIELL EXECUTRIX OFSAID FRED- nuts a which bind on the lugs and force I i the nut 20screwed on to the Preferably the threads on the upper end of left-handedso that when i which support the packages of material being treate Thekeiris shown as arranged to accommodate eight units supported verticallybetween the false-bottom 4 and the head 23, but it is preferable toarrange one of the units to be free from the head 23 so that-testsamples of the material may be removed from the keir through a hand-holein the top to examine the same during the dyeing or other process. Toprovide for this, this unit is constructed with separatecompressionmeans of its own, as shown in Fig. 6 and hereinafter morefully described, and is supported in the keir independent of the head23. The head 23 has only seven hubs around the rim 26 and these arespaced one eighth of the circumference apart with the eighth hubeliminated and the rim bowed in at 29 to provide space for gainingaccess to the free unit. A hand-hole 30 is provided in the dome 2, seeFig. 1, which has. a cover 31 adapted to be screwed down into its seatby means of the hand lugs 32-32. The hand-hole 30 is located on thequarter on the dome 2 to correspond with the position of the bowed-inportion 29 of the rim 26, so that test samples may be removed from thefree unit and taken out through the hand-hole without interference withthe head 23. The head 23 is-secured to the end of .the spindle 12 by itshub 24 which is held against a shoulder 33 by a nut 34 screwed on to theend of the spindle. To prevent the head 23 from turning in the keirunder influence of the turning movement of the hand-wheel, twodiametrically opposed guiding lugs 35-35 are provided on the oppositebosses 27-27, adapted to slide in grooves -in the gulding pieces 36-36which are formed of channel iron and bolted to the inside of the keir,see F ig. 2.

The units for supporting the packages of yarn to be dyed or otherwisetreated are similar in general arrangement to those shown in the patentof John C. Hebden and Frederick'H. Daniell, No. 996,761, dated July 4,1911. Specifically, they are constructed as follows and embody certainimprovements as shown in Figs. 2 and 6 and now described: The yarn'orother material is wound on poroustubes which are capable of longitudinalcontraction, such forms of i tubesbeing shown in the'patent of FrederickH. Daniell, No. 974,126 dated November 1, 1910, and the patent ofFrederick H. Daniell and John C. Hebdefi, No.

974,127, dated November 1, 1910. Any of the forms of tubes shown anddescribed in these applications might be made use of, but We havepreferred to here illustrate the one first disclosed, which consists ofa helically coiled wire serving as a support for a tubular fabric sleeveand constituting a porous, non-collapsible tube capable of axialcontraction under compression. In Fig. 6, such a form of tube 37 isshown in section with the hehcally coiled wire 38 serving as a tubular,ribbed framework for distending and supporting the fabric covering 39."The dot-and-dash lines indicate the yarn mass surrounding the tube, andas here illustrated the mass is shown as consisting of a plurality ofcops or cheeses 40-40, etc., wound with separate yarns on one continuoustube with the ends of the packages abutting each other. This is thepreferred method of winding the packages for dyeing warps having aplurality of ends, but it is obvious that a single end might be wound onthe tube with a traverse extending from end to end of the latter; o-r anumber of packages of lesser traverse might be Wound on shorter tubesand stacked end for end as specified in our patent, No. 996,761,previously referred to.

In whatever form it is preferred to wind the packages the means forsupporting the units between the diaphragm 4 and the head 23 will 'bethe same. This consists of a stringer 41 whichis preferably formed ofangle-iron, see Figs. 2,6 and 10, to provide for a three point hearingwithin the tube 37 without obstructing the latter to prevent the flow ofthe liquor through the tube. As

shown in Fig. 2, the stringers 41-41 have rimmed flanges 42 and 43 ateach end adapted to press'upon the ends of the packages to effect thecompression of -theyarn mass. The stringers for the units which are heldat the top by the head 23 are arranged as follows: The upper flanges42-42 are secured to the ends of the stringers 41-41 by means of thecentral triangular-shaped lugs 44, see Fig. 2, adapted to fit the insideof the angle iron and fastened thereto by the rivets 46-46, or by othersuitable means. The lower ends of the stringers project through centralopenings in the flanges 43-43 and are formed with bosses 47-47 throughwhich the set screws 48-48 are screwed.

The packages of material are strung on to the stringers 41 against thefixed flange 42, and the removable flange 43 'is then applied to theopposite end of the stringer. The packages are compressed sufficientlyto allow the flange 43 to pass beyond the screws 48-48 and these latterare then adjusted to hold the flange in position on the stringer, asshown in Fig. 2.- V

' The flanges 43 areremovably secured in openings in the diaphragm 4 inthe followin manner." The diaphragm plate 4 is I I provi ed. witheightopenings49-49, etc.,

arranged in a circle with their centers in line with the centers of thehubs 28-28 etc., on the compression head 23.. Adapted to these openingsare socket members 50-50' formed-with shouldered sleeves: extendingthrough the plate 4 and secured in position by the nuts 5151 screwed onto their threaded ends. The sockets in the upper part ofthe members 50are formed with interrupted threads 52- 52, see Fig. 8, and a sleeve 54on the lower side of the flange 43 is adapted to enter the socket and isformed g5 terial' is interposed between the end of the sleeve 54011 theflange 43 and a shouldered seat 57 in the socket 50 to make the jointtight.

The upper flanges 42 are provided with central studs or projections45-45, and when the lower flanges are in position in their socketsthesestuds will aline with the openings in the hubs 28 of the head 23. Forconvenience in adjusting the head 23 down into proper engagement withthe flanges 42 we make use of .slip bushings 5858 arranged to slide inthe hubs 28 and bored to receive the studs 45. The bushings 58 are madeconsiderably longer than the hubs 28 and when the head 23 is raised fromthe flanges 42 they will slide down through the hubs, being preventedfrom dropping out by the projecting rims 59-59 formed on their upperends. The head 23 is raised to allow the placing of the units with theirflanges 43 in the sockets 50 and the bushings 58 will then extend downthrough the hubs 28 and can be fitted over the studs 45. When the headis lowered the bushings will guide the studs into 'proper engagementwith the openings in the hubs to centralize the units in their bearings.

In Fig. 6 is shown the free unitfrom which test samples may be removedfrom the keir through the hand-hole 30. The lower flange 43 issubstantially the same in construction as the lower flanges for theother units, but the upper flange 60 in this case, instead of beingsecured to the end'of the stringer 41, is removable from the stringerand adapted to be adjusted in the direction of-the length of the latter.In this arrangement'th angle-iron portion of thestringer is shorter thanthat of the other stringers and is provided at. its upperend 61'connected to the angle-iron by a transverse pin 62 driven through bosses63-453. The bolt 61 projects through a central hole in the hub 64 on theflange 60 and is threaded to receive a hand-nut65. Preferably the hub ofthe hand-nut is formed with a conical bearing fitted to a similarlyshaped counterbore in the hub 64. The

lower end of the stringer 41 is here shown as formed with lugs 66-66,see Fig. 10, which take the place of the set screws shown in connectionwith the other stringers and serve as permanent stops to abut the underside of the flange k 43 and prevent the stringer" from being drawnthrough the opening in the latter.

with an extension consisting of an eye-bolt The diaphragm 4 divides thekeir A into two compartments or chambers and the units are supported inthe upper chamber between the false-bottom 4 and the com ression head23. By the arrangement 0 the lower supports for the units justdescribed, the socket members 50 provide a direct communication from thelower chamber to the interior channels extending through the tubes onwhich the yarn is supported. The

diaphragm 4 also has another orifice 69 arranged centrally andregistering with the flanged end of an elbow pipe 71 which is boltedtothe diaphragm. The elbow 71 extends through an enlarged opening in thebottom 3 of the keir and is connected at its opposite end to the flangedquarter-bend pipe 72, see Fig. 1. The quarter-bend 72 is connected tothe straight pipe-section 73 and it will be seen that these connectionsform a channel for the ingress or egress of the fluid to and from theupper chamber of the keir. The lower chamber also has an ingress oregress channel of pipe connections arranged as follows: Riveted to thebottom of the keir and registering with the opening 70 .in the latter isa V-shaped trough-like casing 7 4, shown in Fig. 1. The

front side of this casing 74 intervenes be-' tween the flanges of theelbow 71 and quarter-bend 72, being provided with an opening registeringwith the openings in the pipes, and the flanges are bolted to the casingand together with the same bolts. To the opposite flat side of thecasing 74 is bolted the flange of a quarter-bend pipe 7 5,

see Fig. 3, arranged the reverse of the quarter-bend 72, and connectedat its opposite flanged end with the straight ipe-section 76 runningparallel to the pipe The casing 74 has an opening registering with theorifice in the connected end of this pipe 7 5 and these latter pipeconnections lead into the casing 74 and thence to the lower chamber ofthe keir A.

The mixing tank Bis mounted on top of the heating chamber C, see Fig. 1,and is preferably of cylindrical form with a funnel-shaped bottomleadintg into a quickope ing valve 80 of usual orm, operated by the handlever 81 to 0 en into the chamber C. The heating cham r 0 consistssimply ofa rectangular box formed of lates bolted together, as shown inFig. 4. n the center of the chamber is a coil of ipes 8282, etc.,supported horizontally on rames 83, two of the latter being used, andpreferably made of rods bent up with the transverse supporting bar 84and the feet 85-85. The pipes 82 are connected by U -bends 8686 arrangedalternately at either end in-the usual manner. employed in theconstruction of steam coils to provide for a continuous circulation ofthe steam back and forth across the length of the chamber C, and thesupply pipe 87 and exhaust pipe 88, see Fig. 1, are connected to theends of the coil and lead to the source of the steam supply, not hereshown. The fluid, either liquor or gas, has a free circulation aroundthe steam coil and can be heated to the proper temperature in thechamber C before it is forced into the keir A.

The fluid passes from the heating chamber C to the keir A through asystem of pipes and valves now explained: The pump D may be of any wellknown construction, preferably of the horizontal type, as shown in Figs.1 and 3, andis situated partly underneath the chamber G with its drivingpulley 90 projecting out at one side and ar ranged to be belted to thesource of power, either an electric motor or an engine drivencountershaft, not here shown. I With the type of pump here shown thesuction pipe 91, see Fig. 3, has a flanged end which is connected to theunder side of the chamber C and the discharge pipe 92 leads out from theunder side of the casing 93 and is connected through a flanged pipe 94to a T-pipe 95 leading up into a four-way valve 96. The pipe 94 ispreferably a T arranged with its flanged branch '97 extending upward,and bolted to this flange is a plate 98 into which is screwed the smallhand-valve99. To the hand valve 99 is connected a small pipe 100 whichleads up around the chamber 0 with its end 101 adapted to discharge intothe mixing tank B. By opening the valve 99 a small quantity of the fluid1s bled from its flow through the T-pipe 94 and discharges intothemixing tank B to create a stirring action and keep the liquorthoroughly mixed as hereafter more fully explained.

The four-way valve 96 is formed with two diverging branches 102 and 103which are connected by their flanges to the flanged ends of the pipes 73and 76 which, respectively, lead into the upper andlower chambers of thekeir A. Leading from the 0pposite side of the valve 96 is a flangedbranch 104 which is connected to a threeway elbow 105 having twobranches 106 and 107. The branch 106 extends upward and is connected toa quick-opening valve 108, from which a union 109 leads'into the mixingtank C, see Fig. 1. The other branch 107 is connected by a union 110 toa valve 111 which, in turn, is connected to a pipe 112. Parallel to thepipe 112 is a similar pipe 113 leading from a quick-opening valve 114which is connected at its opposite end to the T-pipe 95 through whichthe fluid from the pump passes into the four-way valve 96. The two pipes112 and 113 are used for. discharge pipes as hereafter more particularlydescribed.

The four-way valve 96 is operated by a lever 115, which is rotated aboutits axis to determine the direction of the flow of fluid through thevalve. the flow throu h the inlet at the bottom of the valve may becaused to pass out through either of the branches 102 or 103 which leadto the upper and lower chambers of the keir,

respectively, or, thevalve may be set to discharge through the branch104. As usual in valves of this well known form, the seat is so arrangedas to provide for two separate directions of flow through the-valve atthe same time. For instance, when the valve is set to take the flowthrough the inlet at the bottom and discharge through the outlet 102,the branch 103 Wlll be connected to the branch 104 and the former can beused as an inlet to discharge through the latter; or,

vice versa, when the inlet at the bottom is connected to dischargethrough the branch 103 the branch 102 will be connected with the branch104. In this way the pressure of the pump D can be arranged to causeacirculation of the fluid from the heating tank through the keir andback again into the tank in two different ways: either through the pipe73, up into the upper chamber of the keir and back through the lowerchamber, thence through the pipe 76, branch 103, into the valve 96 andout through branch 104; or, from the valve 96 through the pipe 76 to thelower chamber of the keir, then through the openings in the false-bottom4 to the upper chamber, and exhausting down through the pipe 71 to thepipe 73, back through the branch 102 into By turning this lever thevalve 96, and out through the branch 104.

Referring to Fig. 1, 116 is a small hand Valve screwed into the top ofthe keir A and connected by a pipe 117 to discharge into the mixingtankB. This valve serves as a vent for the steam and gases given off by theboiling liquor in the keir and prevents back pressure in the latter. Awater gage 118 is provided on the outside of the keir to show the levelof the fluid and two pressure indicators 119 and 120 are arranged inconvenient positions as shown. The indicator 119 has a pipe leading fromthe upper chamber of the keir and the pipe to the indicator 120 'ortubes 37, shown in Fig. 6, and in this form the cops or bundles areplaced on the'stringers 41, to be supported in units for SllbJGC- tionto the dyeing or other process. There are preferably seven fixed unitsarranged as shown in Fig. 2, with an eight free unit as shown in Fig. 6,which latter will hereafter be referred to as the test unit. The cops ontlie fixed units are held on the stringer 41 against the fixed flange 42and the removable flange 43 is placed in position and pressure appliedto force this flange toward the fixed flange. After the flange 43 isforced onto the stringer 41 beyond the screws 48 these are adjusted tohold the flange in place and the units are ready to be placed in thekeir. The cops are placed on the test unit, shown in Fig. 6, with oneend against the flange 43 and the flange 60 is then applied to theopposite end with the bolt 61 extending through the hub 64. The hand-nut65 is next screwed down on the bolt againstthe flange and the latterwill be forced toward the flange 43 which is held by the lugs 66-66. Asthe flange 60 is forced downward the cop support 37 will yield underpressure and contract longitudinally while the yarn mass is beingcompressed. Sufficient pressure is applied to the flange 60 to compressthe yarn to a oint where all portions of the mass are 0 the samedensity. After the yarn has been prepared in the manner above describedthe door a is opened and the units placed inside the latter. The head 23is first raised by turning the hand-wheel 18 to the left and the lowerflanges on the units are set into the sockets 50 and screwed intotheirseats; The slip bushings 58 are next engaged with the studs 7 45 onthe flanges 42 and the head 23 is then lowered by means of thehand-wheel 18 to be brought down against the flanges. If it is desiredto apply pressure to the yarn after the units are in position in thekeir the hand-wheel 18 is turned to cause the head 23 to exert pressureon the flanges to give a further compression of the yarn on the fixedunits and the stringers 41 will slide down through the openings in thelower flanges 43.. The yarn on the free or test unit is compressedbefore placing the latter in the kei'r and in some cases it has beenfound more convenient to compress the yarn on the fixed units to theproper density before plac in them in osition. This may be accompllshedby p acing the units in a suitable press and arranging the adjustingscrews 48 in such position on the stringers 41 that they will beproperly placed to hold the lower flanges after the yarn is compressedto the maximum extent requlred. It will also be obvious that instead ofusing the stringers with fixed upper flanges, as shown in Fig. 2, the

units mlght all be arranged similar to the test unit illustrated in Fig.6 with a se arate compression means on each stringer. n the latter casethe hubs 28 on the head 23 would engage the ends of the bolts 61 and thehead- 23 would be used simply as a supporting means to locate and holdthe upper ends of the units and steady them in their posit-ions. Thepreferred arrangement, however, is to make use of the head 23 as acompression means for applying the pressure to a plu- 'rality of theflanges at one time, thereby providing for greater convenience andexpedi tion in performing the operation. After the units are all inposition in the keir, with the material held under compression asdescribed, the door a is secured in posit-ion and the apparatus is readyfor the dyein or other process. The d e-liquor or other iluid is pouredintothe mlxing tank B wit-l. the

valve 80 open to allow it to flow down into the heating chamber C.Preferably, enough fluid is poured in to fill both the tank B andchamber C. The steam is turned on at-its source of supply and enters thechamber C through the pipe 87, circulating through the steam coil withinthe chamber and exhaust-- ing through the pipe 88, which preferablyleads to a condenser. After the fluid is properly heated the pump D isstarted and the fluid is sucked down from the chamber C through theintake pipe 91 and forced through the discharge pipe 92 and T-pipe 94 uinto the four-way valve 96, the valve 114 being closed. The valve 96 isset to connect the inlet at its bottom, which leads from the T-pipe 95,with the rear branch 103 and the fluid will be forced through the pipe76 into the lower chamber of the keir. The continued pressure of thepump causes the fluid in the lower chamber to be forced up through theorifices in the diaphragm 4, through the openings in the sockets 50 andflanges 43, and into the interior channels of the tubes which supportthe yarn. A column of fluid will be raised'in the interior, axialchannel of each unit and, the tubes which support the cops being orous,the liquor will be forced out throug the walls of the tubes to radiatethrough the yarn and permeate the whole mass.

When the valve 96 is set as above described with the outfiow leadingthrough the branch 103 the front branch 102 will be connected with theopposite side branch 104 which leads into the three-way elbow 105. Thevalve 111 is kept closed and the valve 108 open, so that a continuouscirculation of the fluid can be kept up, from the heat ing chamber intothe lower chamber of the keir; through the yarn masses on the units intothe upper chamber; then back again to the heating chamber.

By setting the, valve 96 with the outflow leading through the frontbranch 102 instead of the branch 103 the circulation of the fluidthrough the keir can be-reversed as follows: The pressure of the pumpwill then force the liquor through the pipe 73 into the upper chamber ofthe keir; through the material, permeating from the outside of the copsto the interior channels in the units; thence down through the openingsin the diaphragm 4; and exhausting from the lower chamber out throughthe pipe 76, valve 96,

and back intothe heat-ing chamber C. Either of these processes can beused, or both, if necessary, and the dye-llquor can be kept circulatingback and forth through the yarn'until a thorough saturation is effectedand the proper shade of color secured. By removing the cover 31 testsamples can be taken from the free unit through the'handhole 30 and theyarn examined to determine the progress of the dyeing operation, Whilethe circulation of the fluid is taking place the bleeding valve 99 isopened and a small stream of the liquor is forced up through the pipe100 and flows into the mixing tank B.. The tank B is preferably keptpartly filled with the liquor and the valve 80 is open during thecirculation, so that the flow from the pipe 100 will serve to stir thecontents of the mixing tank and cause a gradual feed-.

ing of the liquor into the heating chamber. This keeps the liquorproperly mixed and prevents any portion of the supply from becomingstagnant. The mixing tank B serves also as an expansion tank during thecirculation of the liquor. The Valve 80 is preferably kept open whilethe pump is running and the fluid is free to rise and fall within thetank B according to the flow from and to the pipe 113 which preferablyleads to a' waste tank or catch basin, not here shown.

The material may be washed in the keir if desired by pumping waterthrough the apparatus in the same manner as the dyeliquor ispumped-through and the water is led ofi' through the discharge pipe 112by closing or part1 closing the valve. 108 and opening the va ve 111.Air or steam may be forced through the material for drying it in thesame way.

It is obvious that various modifications might be made in the form andarrangement of the apparatus without departing from the scope of ourinvention.
